When a tool (cutter/hammer) has to be replaced, it is advisable to replace the whole set. The use of
non-original tools might cause irregular vibrations on the machine.
If replacing operations are carried out with the machine lifted up, do not rely only on the hydraulic
lifter of the machine: it is recommended to place mechanic props or trestle supports between the
machine and the soil, thus preventing the head from suddenly and dangerously falling down.
DRIVE BELTS REPLACEMENT
To replace the belts proceed as
follows (picture 11):
-
Remove roller C by
unfastening its tensioning
spring, unscrewing nut
B with
a 32 mm key and holding pin
A with a 22 mm key
-
Remove the damaged belt(s)
-
Position the new belt(s)
-
Proceed in reversed order to
reassemble the tensioning
roller, by properly adjusting
the tension of the belts (see
chapter “Adjustment of belts
tensioner”, page 22)
Picture 11
If a belt gets damaged, it is recommended to replace the whole set, in order to have the drive
tension equally balanced on each belt.
The pulleys are made integral to the transmission shaft by means of locking assemblies.
The torque to be applied to clamping screws is 17 Nm.
